Abstract

A method and means for obturating a stub case on the barrel wall of a firearm is disclosed having an annular bead located near the top of the stub case wall dimensioned so as to provide an annular gap between the bead and the barrel wall thereby throttling the streams of gas flowing back after detonation. The gas is thus permitted to expand and is deflected in a Y-shaped packing ring so that the radial pressure of the gas against the oblique arm of the packing ring provides a satisfactory obturating action.
